Question

操作按钮正确，它执行所有之前的行。但是，实例化email对象时会显示错误。

   public void send(View view){
    EditText text = (EditText) findViewById(R.id.editText);
    Switch iluminacao = (Switch) findViewById(R.id.switch1);
    Switch wifi = (Switch) findViewById(R.id.switch2);
    RatingBar mBar = (RatingBar) findViewById(R.id.ratingBar);
    System.out.println(text.getText().toString() + iluminacao.isChecked() +
                       wifi.isChecked() + mBar.getNumStars());

    Email email = new Email();
    email.sendEmail(text.getText().toString(), iluminacao.isChecked(),
                    wifi.isChecked(), mBar.getNumStars());
}

Email.Java

package com.morais.daniela.conectasp;
import android.os.Build;
import org.apache.commons.mail.DefaultAuthenticator;
import org.apache.commons.mail.EmailException;
import org.apache.commons.mail.SimpleEmail;

public class Email {
private SimpleEmail email = new SimpleEmail();
//FIXME
//Adicionar email correto para onde deverá ser enviado!
public Email() {
    email.setSSLOnConnect(true);
    email.setHostName("smtp.gmail.com");
    email.setSslSmtpPort("465");
    email.setAuthenticator(new DefaultAuthenticator("conectasaopaulo@gmail.com.br","senha"));
}

public void sendEmail(String comments, boolean getIluminacao, boolean getWifi, float getStars){
    String iluminacao = "Não.";
    String wifi = "Não.";
    if(getIluminacao==true) {
        iluminacao = "Sim.";
    }
    if(getWifi==true) {
        wifi = "Sim.";
    }
    try {
        email.setFrom("conectasaopaulo@gmail.com.br");
        email.setDebug(true);
        email.setSubject("Feedback - ConectaSP");
        email.setMsg("Houve problemas com a iluminação? " + iluminacao + "\n\n"
                     + "Houve problemas com o wifi? " + wifi + "\n\n"
                     + "Avaliação geral " + getStars + "\n\n"
                     + "Comentários:\n" + comments + "\n\n"
                     + "Informações gerais do aparelho\n" + Build.DEVICE + "\t" + Build.HARDWARE + "\t" + Build.MODEL);
        email.addTo("dani.m@hotmail.co.uk");
        email.send();
    } catch (EmailException e) {
        System.err.println("Erro ao enviar email.");
    }
}
}

请检查以下代码：

 private SimpleEmail email = new SimpleEmail();
    //FIXME
    //Adicionar email correto para onde deverá ser enviado!
    public Email() {

if(email==null)
email = new SimpleEmail();

email.setSSLOnConnect(true);
email.setHostName("smtp.gmail.com");
email.setSslSmtpPort("465");
email.setAuthenticator(new DefaultAuthenticator("conectasaopaulo@gmail.com.br","senha"));
}

并检查清单文件中有关电子邮件的权限。

为什么不能通过单击我的按钮来实例化对象？
